IMPROVEMENT IN HORSESHOES.

Specification forming part of Letters Patent No. 189,718, vdated April17, 1877 application filed February 1, 1877.

To all whom it may conce/rn:

Be it known that I, SIMON P. FisHEE, of Franklin township, in the countyof Beaver and State of Pennsylvania, have invented certain new anduseful Improvements in Horseshoes; and I do hereby declare the followingto be a full, clear, and yexact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification, in Which- Figure l is a side elevation. Fig.2 is a vertical longitudinal partial section. Fig. 3 is a bottom view.Fig. 4 is a section on .fr m of Fig. 3. Fig. 5 is a detail.

This invention relates to improvements in horseshoes and consists in theconstruction and combination of parts, as hereinafter more fullydescribed and claimed.

The shoe proper in general appearance does not depart from the acceptedstandard, and in construction varies only in the fact that the toe andheels are swaged in suitable dies, in order that, without any furthermanipulation, they may accurately fit the clamps and chisel-calks whichconstitute the remainder of my invention.

A designates the shoe, having the toe c and heels b, whose horizontalsection may be of any suitable shape-rectangular or otherwise.

I prefer to make the toe a with its front curved to correspond with thecurve of the shoe, and inclined slightly outward toward the base. Theheels I prefer to make rectanguiar.

I next construct a clamp, C, for the toe, and clamps d for the heels.Clamp O is made to surround the toe, and lit it closely on the sides andrear, but large enough in front to leave a slit for, the insertion ofthe calk. Clamps d are similar, but made to brace against shoulders sformed on the heel at about the line of the under surface of shoe A, andso fitted as to leave va slit at the rear iustead of at the front.

All the clamps are made broad beyond the slit, to afford more surfacefor gripe, and are so constructed that the slit constitutes a wedge-likeopening, the broad portion being at the bottom.

So formed, the clamps are all placed in position, and the under surfacesof the heels and toe set7 slightly with a hammer, so as to keep theclamps from dropping off during subsequent operations or repairs.

The calks proper consist of inverted Wedges B, with the thick end of theWedge beveled oii to an edge, either a double bevel or single to eitherside being given. This forms a winter-calk.

The heel-calks are rectilinear; but I prefer to make the toe-calk of aconcavo-convex form to suit the shape of the shoe.

The calks B are inserted thin-end foremost into the slits fromunderneath, and driven home tightly, after which the shoe is fastened tothe hoofl in the usual manner.

It is obvious that the pressure exerted by the horse will always tend tomore securely tighten the calks. The toe-calk may be made long enough toform a toe-clip above the shoe or not, as desired.

The summer-calk B is shown in Fig. 5, being substantially identical withcalk B, except that it has an upset end shonldering against the toe andheels underneath.

The shoe is easily constructed, all that is necessary being aswaging-die to give the toe and heels the proper form and size. A blowor two sets them in the die, and they then require no filing or iittingWhatever.

In practice I make the clamps of wroughtmetal and the calks of hardenedsteel; but both may be of steel or other material without departing frommy invention.

The toe and heels may be beveled down to the calks, and the latterextend but a triie below, thus approximating the construction of arodents tooth, the hard material being at the edge, and the soft in thebody. Thus the comparative wear would preserve the conditions ol' edgeand bevel.
